There is improvement when you look the glass. Have you tried turning the sharpening all of the way down. I have read in an article that the first thing they do with a camera is turn the sharpening down and simon40 is getting good results this way as well. My results are that noise is diminished with sharpening all the way down.

How well do you like the sx150. I have been looking for a bargain camera that may not be the latest technology but takes nice pictures.

I kept the sharpening at the middle, which I believe is the default. Turning all way down made a few look like cell phone photos (maybe it's just me).

I am not happy at all with the SX150. It is good only when there is enough sunlight (yes, sunlight only) and when the ISO is 100. Period.

My previous SX110 IS was a great camera. My supposed upgrade back fired.
I think stuffing more pixels into the same sized sensor caused a large trade off as I read everywhere on the internet.

I ended up getting the IXUS 300 HS which is a brilliant cam by the way.

What is your budget? If you can stretch a bit, get the SX 230 HS. It is a fantastic little camera.
